Tiny microheaters that can prompt chemical changes in surrounding material may provide the means to more easily grow replacement tissue for injured patients and form the basis for medical sensors that could quickly detect pathogens, according to researchers at the University of Washington who are the first to demonstrate the process.
The key to the technique, according to Associate Professor Karl Böhringer in the UWs Department of Electrical Engineering, lies in temperature-driven changes in the material with which the less-than-one-millimeter-wide electric heaters are coated. Proteins stick to the material as its temperature rises, and release when it goes back down. That, according to Böhringer, opens the door to a wide array of possibilities.
"The proteins stick locally to the areas we heat, and we can stick cells to the proteins," he said. "This provides a relatively simple, low cost way of creating cell chips to run experiments and to create other useful devices."

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
